Abstract

Es wird eine Prüfmaschine zur gewichtsbelasteten Prüfung, insbesondere zur Druck- oder Härteprüfung, von Werkstoffen beschrieben, die ein Gehäuse, ein bewegbares Prüfelement, eine Belastungseinrichtung für das Prüfelement sowie eine Kraftübertragungseinrichtung zur Verbindung des Prüfelementes mit der Belastungseinrichtung aufweist. Hierbei ist die Belastungseinrichtung innerhalb des Gehäuses der Prüfmaschine angeordnet und umfaßt eine Vielzahl von Gewichten sowie eine Steuervorrichtung. Um die Anzahl der wirksamen Gewichte und somit die auf den Werkstoff einwirk­ ende Kraft zu variieren, weist jedes Gewicht einen vor­ springenden oder zurückspringenden Abschnitt auf, der durch Drehung der Steuervorrichtung relativ zu der Vielzahl der Gewichte oder umgekehrt mit einer in der Steuervor­ richtung angeordneten Ausnehmung oder einem Vorsprung derart in Eingriff bringbar ist, daß dieses und die darüber an­ geordneten Gewichte bei der Prüfung unwirksam sind. Eine derartige Drehung wird durch Betätigung eines außen an der Prüfmaschine angeordneten Betätigungselementes her­ beigeführt. It becomes a testing machine for weight-bearing Testing, especially for pressure or hardness testing, by Materials described that are a housing, a movable Test element, a loading device for the test element and a power transmission device for connecting the Has test element with the loading device. Here, the loading device is inside the housing arranged the testing machine and includes a variety of Weights as well as a control device. To the number of effective weights and thus the effect on the material Varying power, each weight has one jumping or receding section on the by rotating the control device relative to the plurality the weights or vice versa with one in the tax direction arranged recess or a projection can be brought into engagement in such a way that this and the above ordered weights are ineffective during the test. A such rotation is activated by actuating an outside of the Test machine arranged actuator introduced.
